SHUTTLE.

Application filed April 13, 1923. Serial No. 631,917.

Q T all whom it may concern:

Be it known that I, JEAN B. DAUDELIN, a citizen of the United States,residing at Fall River, county of Bristol,' Common wealth ofMassachusetts, have invented cer tain new and useful Improvements inShuttles, of which the following is a specification.

This invention relates to automatically threading shuttles for use inweft replenishing looms, and involves certain improvements over theshuttle described and claimed in my prior application Serial Number530,190, filed January 18, 1922, to which reference is made asillustrating the type of shuttle involved herein.

y directed to the means for guiding the weft through the shuttle eye,and consists in the novel construction, combination and relation ofparts described and illustrated in the accompanying specification anddrawings and particularly pointed out in the appended claims. vThroughout the specification and drawings like reference characters arecorrespondingly applied, and in the drawings Fig. 1 is a partial planview at the thread- .ing end of an automatic loom shuttle of standardtype equipped in accordance with my invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is an end view of the automatic threader removed from theshuttle, and

Figs. 4 and 5 are diagrams illustrating the threading action, Fig. 4showing the position of the weft in threading the shuttle, and Fig. 5the position thereof after the shuttle has been threaded.

I have indicated generally at T-an automatic threader in accordance withmy invention. The threader is mounted in approximately the longitudinalaxis of the shuttle throat and as here shown is a metal castingcomprising a top wall 1, a depending vertical side wall 2, a horizontalbottom wall 3 and an up-turned extension 4 definingwith said walls 2 and3 an open ended recess within which is mounted a thread guide 5.- V f iThe guide 5-is preferably a helical coil, the outer end of which is bentsubstantially vertically downward as indicated at 6 to overlie theup-turned wall 4 of the threader. The extension 6, wall 4 and theopposite side wall 2 of the threader are pierced by a hole for thereception of an anchoring screw present invention is particularly -8which passes transversely through the throat of the shuttle from side toside thereof, I v The upper face of the outermost turn of th guide coilis notched as indicated at 9 and said notch acts to prevent the weft Wfrom slippingoff'the guide as it is drawn from the weft carrier 10 ofthe shuttle. The weft passes into the space between the outer turn ofthe guide and the anchoring portion 6 thereof and-inasmuch as thehelical coil is preferably wound opposite to the unspooling action ofthe weft, the weft as it unwinds works its way towards the center ofsaid coil where it is held against improper escape, being centered bythe notch 9.

At its forward end, the top wall of the threader is provided with adownwardly ex tending guide surface 11 which is disposed substantiallyin line with the outer side wall of the threader. Adjacent and spaced 1from said guide surface 11 is a downwardly turned tongue 12 betweenwhich and said guide surface the weft passes from the helical coil tothe threading eye of the shuttle when the shuttle is being threaded. Ex-

tending as a continuation of the guide surface .11 is a verticallydisposed snubbing post 13. Rising vertically from the bottom of theshuttle eye is a snubbing post 14.

The posts 13 and 14 are disposed substan- I tially in line with eachother at the inner end of the threading eye and in effect define theinner'end of said eye. In. addition toits guiding function the post 14also assists to center the threader in the shuttle, the upper wall ofthe threader being pierced by a hole to receive said post. Beyond thepin 13, the top wall of the threader slopes downwardly and rearwardly asa guiding tongue 19. This tongue is tapped and threaded to receive ananchoring screw 20-.

The outer end of the threading eye is de fined by a pair of spacedvertically disposed guide pins 15 and 16 which are clinched within thewood of the shuttle. At its upper end the pin 15 is bent over uponitself as indicated at 17, and extended across the delivery end of thethreading eye to provide a guide for the weft effective to direct theweft in the eye during the threading of the shuttle and constituting anoverlying guide to prevent improper escape of the weft from the eye by adirect upward lifting movement after the shuttle has been threaded. Theterminus of the angularly' bent portion 17 of said guide pin 15 isdisposed in a notch 18 out in the wood of the shuttle at the left handside of the threading eye as viewed in Fig. 2, so that in threading theweft passes from the. helical coil 5 around the snubbing post 13, underthe clown-turned tongue 19 at the forward end of the threader and isdeflected along said guide portion 17 into the notch 18 from which itpasses under the guide portion 17 into the threading eye. (See Fig. 4-.)The shuttle is now threaded and the weft drawsdirectly past the snubbingpost 14 and out between the pins 15 and 16, as shown in Fig. 5.

Various modifications in the form and construction of my device mayobviously be resorted to, all without departing from the spirit of myinvention, if within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

1. In a shuttle having a threading eye, a threader mount-edlongitudinally of the shuttle throat and having a guide disposedtransversely to the axis of said eye, a pair of spaced snubbing postsdisposed in sub stantially longitudinal alignment with each other anddefining the intake end of the threading eye, a pair of spaced guidepins disposed in substantially longitudinal alignment with each otherand defining the delivery end of said eye, one of said guide pins beingextended across the threading eye and constituting a guide for directingthe weft into said eye as it draws past the forward snubbing post inthreading and a barrier for preventing escape of the weft from said eyeas it draws past the rear snubbing post after the shuttle has beenthreaded.

2. In a shuttle having a threading eye, a threader mountedlongitudinally of the shuttle throat and having a guide disposedtransversely to the axis of said eye, and a depending verticallydisposed snubbing post, a snubbing post spaced from and disposed insubstantially longitudinal alignment with said first named post anddefining the intake end of the threading eye, a pair of spaced guidepins disposed in substantially longitudinal alignment with each otherand defining the delivery end of said eye, said pair of guide pins andsaid pair of snubbing posts being arranged in substantially horizontalalignment relative to each other, and the upper end of the guide pinaligned with the forward snubbing post being extended across thethreading eye and constituting a guide for directing the weft into saideye as it draws pastthe forward snubbing post in threading and a barrierfor preventing escape of the weft from said eye as it draws past therear snubbing post after the shuttle has been threaded.

3. In a shuttle having a threading eye, a

threader mounted in the shuttle throat and having a helical guide coildisposed transversely to the axis of said eye, said coil having a notchin its outermost turn effective to prevent the weft from slipping offthe coil, a pair of spaced snubbing posts defining the intake end ofsaid eye, and a pair of spaced aligned guide pins defining the deliveryend of said eye.

4. In a shuttle having a threading eye, a threader mounted in theshuttle throat and having a tongue overlying the threading eye, a guidepin at the delivery end of said eye and having its upper end extendedtowards the opposite side of the threading eye and spaced therefrom topermit passage of the weft running over said bent portion into the eyein threading the shuttle, said bent portion when the shuttle is threadedconstituting a barrier overlying the threading eye and effective toprevent escape of the weft by direct upward lifting movement.

5. In a shuttle having a threading eye, a threader mounted in theshuttle throat and having a downwardly turned tongue overlying thethreading eye, a guide pin set through the wood of the shuttle at thedelivery end of said eye and having its upper end bent downwardly andextended towards the opposite side of the threading eye and spacedtherefrom to permit passage of the weft running over said bent portioninto the eye in threading the shuttle, said bent portion when theshuttle is threaded constituting a barrier overlyingthe threading eyeand effective to prevent escape of the weft by direct upward liftingmovement, and a pair of spaced vertically disposed posts at the innerend of the threading eye, one of said posts constituting a snubber pastwhich the weft is drawn into said eye during the threading action of theshuttle and the other post constituting a snubber past which the weftruns directly into said eye after the shuttle has been threaded.

6. In a shuttle having a threading eye, a threader mounted in theshuttle throat and having a tongue overlying the threading eye and aguide in rear of said tongue and disposed transversely to the axis ofsaid eye, a pair of guide pins defining the delivery end of said eye,one of said pins bent over at its upper end and extended towards theopposite pin but spaced therefrom to permit passage of the weft runningover said bent portion into the eye in the threading of the shuttle,said bent portion when the shuttle is threaded. constituting a barrieroverlying the threading eye and effective to prevent escape of the weftby direct upward-lifting movement. e

, 7. In a shuttle having athreading eye, a

threader mounted in the shuttle throatiand posed transversely t0 theaxis of said eye, a pair of guide pins defining the delivery end of saideye, one of said pins bent over at its upper end and extended towardsthe opposite pin but spaced therefrom to permit passage of the weftrunning over said bent portion into the eye in the threading of theshuttle, said bent portion when the shuttle is threaded constituting abarrier overlying the threading eye and effective to pre-' vent escapeof the weft by direct upward lifting movement, and a pair of spacedvertically disposed posts defining the inner end of the threading eyeand aligned with said pair of guide pins, one of said posts c0n-.stituting a snubber past which the weft is drawn into said eye duringthe threading action of the shuttle and the other post constituting asnubber past which the weft runs directl into said eye after the shuttlehas been t readed.
